beta phellandrene/abies

The composition of the steam-distilled essential oil from the leaves of Abies sachalinensis (F. Schmidt) Mast. cultivated in Hokkaido (Japan) was studied by GC-MS. The seasonal variation in the main volatile constituents was also investigated. Analysis of the essential oil resulted in the

Grand fir (Abies grandis) is a useful model system for studying the biochemistry, molecular genetics, and regulation of defensive oleoresin formation in conifers, a process involving both the constitutive accumulation of resin (pitch) in specialized secretory structures and the induced biosynthesis

Of ten terpenes that comprise most of the volatiles of grand fir foliage only four were affected by addition of nitrogen. Levels of beta-phellandrene, camphene and bornyl acetate and terpinolene were significantly reduced with nitrogen added to the equivalent amount of 44.8 g/m2. A quantity of 22.4

A cell-free extract from the xylem of lodgepole pine (Pinus contorta) catalyzes the conversion of [1-3H1]geranyl pyrophosphate to a variety of monoterpene olefins found in lodgepole pine oleoresin. This monoterpene synthase activity is similar to previously described terpenoid cyclases from grand

UNASSIGNED Synechocystis (a cyanobacterium) was employed as an alternative host for the production of plant essential oil constituents. β-Phellandrene synthase (PHLS) genes from different plants, when expressed in Synechocystis, enabled synthesis of variable monoterpene hydrocarbon blends,

The essential oil of silver fir (Abies alba) is known to help respiratory system and have easing and soothing effect for muscle. In the present study, we investigated the chemical composition, cytotoxicity and its biological activities of silver fir (Abies alba) essential oil. The composition of the

Constitutive and inducible terpene production is involved in conifer resistance against bark beetles and their associated fungi. In this study 72 Norway spruce (Picea abies) were randomly assigned to methyl jasmonate (MJ) application, inoculation with the bluestain fungus Ceratocystis polonica, or
